Framing work progresses, as Dan Enright and crew work on the home's hip roof, as well as the truss system over the garage. In the basement, Bob talks to Tim Woods (from Internet Home Alliance) about the special wiring that is being installed to make this farmhouse a "connected" home.

Bob tours NASA's Johnson Space Center in Houston, TX, where he explores the mock-up of an international space station. Mike Hawes, the Deputy Associate Administrator at the Johnson Center, remarks that the space station is "the ultimate smart house."

Dr. Jeff Wisoff, a former astronaut, guides Bob around the high-fidelity mock-up, which closely resembles the actual space station.
